Question
A can of Pepsi is supposed to have a mean volume of 12 ounces. Both overfilling and under-filling are undesirable. If either occurs, the machine that fills the cans has to be readjusted. The bottling company wants to set up a hypothesis test so that the machine has to be readjusted if the null hypothesis is rejected. Set up the null and alternative hypothesis for this test.
H0 : µ = 12 and Ha : µ > 12
H0 : µ = 12 and Ha : µ 12
H0 : = 12 and Ha : 12
H0 : µ = 12 and Ha : µ < 12
a.H0 : µ = 12 and Ha : µ > 12
b.H0 : µ = 12 and Ha : µ 12
c.H0 : = 12 and Ha : 12
d.H0 : µ = 12 and Ha : µ < 12
Explanation / Answer
Since both overfilling and under-filling are undesirable so test will two tailed. Hypotheses are:
H0 : µ = 12 and Ha : µ 12
b.H0 : µ = 12 and Ha : µ 12
